The increasing demand for sustainable energy has spurred research and development of wind turbines. In this study. a passive flow-control technique using a non-uniform curved slot is proposed. The slot is engraved on the mid-chord region of the National Renewable Energy Laboratory (NREL) Phase VI wind turbine blade. https://www.spidertattooz.com/Makita-RF1101-2-1-4-Hp-8-000-24-000-Rpm-11-0-Amp-Variable-Speed-Router/
